Tsuki

A night-sky companion who lives in your voice channel — listening, thinking, and answering out loud, around the clock.

Online 24/7 on Discord

About

Tsuki is a self-hosted AI companion. She sits in a Discord voice channel, hears when you speak, understands the room's context, and replies with her own synthesized voice — no button presses, no wake words. Between turns she remembers what matters to you, so conversations pick up where they left off.

She started as a desktop app for late-night chats and grew into a persistent presence: the same persona and memories, available from anywhere Discord is.

How she works

  1. She listens

    Voice activity detection splits the channel audio into turns, which are transcribed by Whisper.

  2. She thinks

    A persona-tuned LLM builds the reply, with semantic search over long-term memory when the moment calls for it.

  3. She speaks

    Her reply is synthesized into a natural voice and streamed back into the voice channel.
